I have added all the necessary open graph metas to my site: http://karma.vote and tried to use the Twitter Card Validator: https://cards-dev.twitter.com/validator
and it fails when using my .vote domain name, however if I use the IP address or another domain (I had to create to redirect to karma.vote) http://lucidlife.co it works. Even when trying to use redirectors/url minifiers like goo.gl, tinyurl and bit.ly it fails the Card Validator unless I enter the IP address or .co domain.
Why does Twitter not acknowledge .vote domains? and how can I get around it other than purchasing another domain it allows? It makes no sense why they would fail some domains if they are valid.
